T0 all w/om tml ay concern:

Be it known that I, EDWARD ERIcKsoN, a subject of the King of Sweden, residing at Lynn, county of Essex, and State of Massachusetts, have invented an Improvement 1n Sewing-Machines, of which the following description, in connection with the accompanying drawing, is a specificatlon, like characters on the drawing representlng like parts. h

This invention relates to sewing machines andespeeially to machines of the lock-stitch type wherein the stitch is made by the interlocking of a needle thread and a shuttle thread. In all sewing machines of this character with which I am familiar, the shuttle is a movable element and the interlocking of the threads is secured by driving the shuttle through a loop formed 1n the shuttle thread. In my improvement the shuttle is a stationaryl yaffair and the interlocking of: the threads issecured by passing the loop of needle thread from t e needle over the stationary shuttle.I

My invention also comprehends a nov-el arrangement whereby the-"awl-carrier is operated from the needle-carrier, thus obviating any separate mechanism for giving the awl its `movement, and said invention also comprehends other novel features relating to the manner of feeding the work and of making the stitch, all as will bc more fully` hereinafter described and then pointed out in the appended claims.

In the drawings I have illustrated in detail a selected embodiment of my invention which .is sufficient to demonstrate the principle of the invention, but I wish it understood that the invention is not confined to the particular constructions illustrated.

Figure 1 is a side view of a sewing machine embodying my invention; Fig. 2 is an enlarged front view of the head; Fig. 3 is an enlarged rear view of the head; Fig. 4 is a view showing the stitching mechanism; Fig. 5 is a plan view of the shuttle and its holder; Fig. 6 is a side view of the shuttle; Figs. 7 and S are views of the stitching mechanism similar to Fig. al, but showing the parts in different positions; Fig. 9 is a side viewof the looping mechanism; Figs. l0 and 1l are plan views of the looping mechanism: Fig. 12 is a side view-of the needle-carrier and needle; Fig. 13 is a front iew thereof; Fig. 14 is a view of the guide kof intermeshing gear wheels are carried by Said shafts respectively.

My improved sewing machine embodies the prlncipal elements usually found in sewmg machines, that is, an awl for penetrating the work, a needle for drawing the loop of needle thread through the work, a looper to loop the thread into the eye of the needle, a shuttle carrying a shuttle thread which is intcrlocked with the needle thread for forming the stitch, feeding mechanism for feeding the work, and a take-up for tightening the stitch. My improved sewing machine, however, differs from prior sewing machines in many features, all as will be more fully hereinafter described.

, The various parts 4of the device are supported on a frame 3 which may have any 85 suitable or usual \`cbnstruction and which carries a cam-shaft 4 on which are mounted the cams for operating the loop-opener and the looper mechanism, and a main or driving shaft 5 on which are mounted the cams 90 for operating the needle, the take-up and the thread-measuring device. The cam-shaft at is driven from the main shaft 5 by means and 7 that main shaft 5 may. be driven in any suitable way, either by a foot treadle or by a driving pulley 8. Vhen said shaft is driven by foot power, the pulley 8 may act as a balance wheel.

being sewed, is supported on a work rest 10 which is herein shown as supported by an arm 1l .secured to the side 300 of the head of the frame 3. The work is held to the work rest by means` of a presser-foot 12 1054 which in the present embodiment has a rising and falling movement to permit feeding of the work and also a lateral movement, all as will be more fully hereinafter described.

This presser-foot is slidably mounted QnLWo 110 The work or material 9, which is pins 13 extending from the head or end 14 of a rising and falling bar 15, the function of which will be more fully hereinafter described. A hand lever 16 pivoted to the frame at 17 and aiso pivoted at 18 to the upper end of the bar 15 serves as a means for manually lifting the presser-foot.

The needle, shown at 20, is a curved needle and is carried by a needle-carrier 21 which is mounted to oscillate on a fixed stud 22 extending from the' side 300 of the frame. This needle-carrier receives its oscillating mqvement from the main shaft 5, and for this purpose said carrier has pivoted thereto at 23 a link 24 which is connected to a crank 25 formed on the main shaft 5. The awl, which is also curved,` is shown at 26 and is secured to an awl-carrier 27 that is mounted to have an oscillating movement about the stud 22 as aA center. The awl-carrier, however, is not mounted on the stud but is mounted to slide in a guiding member 28 which is provided with the curved way 29 into which fits a curved rib 30 formed on the awl-carrier. The awl is bperated by the needle-carrier and for this purpose said awl-carrier has projecting therefrom a stud 31 which extends into and through a` curved slot 32 formed in the needle-carrier so that when the needle oscillates, the pin 31 will be engaged by the ends of the slot 32 and the awl-carrier will thus be Agiven its proper movement. For instance, when the partsare in the osition shown in Fig. 4 with the needle inserted through the work, the awl will be retracted and upon movement of the needle-carrier from the position shown in Fig. 4 to that shown in Fig. 7, the awlwill remain stationary because the slot 32 will merely move over the pin 31. Upon further movement of the needle-carrier into the position shown in Fig. 8, however, the awl-carrier is moved with the needle-carrier, thus lcausing the awl to penetrate the work. One advantage of thus operating the awl-carrier from the needle-carrier is that the number of parts is reduced and the mechanism is simplified.

The thread t, whichmay be taken from any suitable source of thread supply, if

first passed through a thread measurer, hereinafter described, then is fed over a uide roll 33, see Fig. 1, through a wax pot 40 of any suitable construction, and from the wax pot over a tension roll 350l and thence over a guide roll 360 to a take-up 370, and from the latter to a looper mechanism which places the thread't in the hook of the needle. This looper mechanism is shown in detail in Figs. 9 to 11, and it comprises a looper and a thread placer. The looper is shown as a member 34 slidably mounted in a block 35 and carr ing at one end an eye 36 through Iwhich t e threadt passes and provided also with a threadholding finger 37 separated from the eye.

to yieldinglyhol'd" t-l1e1thread against the.

finger 2. :The-', inge 37 and spring 38 constitute an .open eye having a 'resilient throat into which .the thread may be placed. The thread placer is shown at 39 and it comprises an arm pivoted at 40 on the block 35 and having at one end a'- lateral extension 41 adapted to engage .the thread and place it between the spring 38 and the finger 37. The looper 34 has a sliding movement through the block 35 and such movement isgiven to the looper by a cam '42 mounted on the cam-shaft 4. The thread placer is operated by a cam' 4 3 also mounted on the cam-shaft 4. When the parts are in their normal positions such as shown in Fig. 1, the arm 41 of the thread placer is below-the thread and the latter passes simply through the eye 36. Vhile the needle is passing down through the work the cam 43 first operates the thread placer to lift the thread up, as shown in Fig. 9, and at the same time, the rise 47 on the cam 42 engages the roll at the end of the looper and forces the same forwardly with the result that the thread is carried in between the finger 37and the spring 38. After this occurs the cam 42 throws the looper forwardly sol that when the needle has completely entered the work, as shown in Fig. 4, the hooked end of the needle will be in line with the space between the eye 36 and the finger 37. The block 35 is mounted to turn laterally, this being provided for' by supporting said block on a stud 44 which is mounted to turn in a art 45v of the frame. When the parts are 1n the position shown in Fig. 4 a cam projection 48 on the cam 42 engages the end of the looper and turns the block 35 laterally, thus swinging'the opposite end ofl the looper Itoward the needle and carrying the portion of the thread between the eye 36 and the finger 37 into the barb or hook of the needle, as clearly seen in Fig. 1l. While the parts are in this position, the needle is retracted, as shown in Fig. 7, and at the same time the looper asses oil from the rise of the cam 42 and 1s returned to its normal position by the spring 49, during which operation the thread is drawn out from between the finger 37 and the spring 38. The block 35 is restored to its normal position by a spring 5() which encircles the stud 44 and is connected thereto .at one end. The loop of thread which is drawn through the work by the needle is then passed over the shuttle so as to be interlocked with the shuttle thread.

In my invention the shuttle is stationary land this interlocking ofthe shuttle thread and the needle thread is secured hy renier ing theloop from the needle and .then pa.

ing it over the stationary shuttle. The shuttle is Shown at l and it .mor 'ed in 5 a shuttle holder 52 whieh is open at adjacent the needle, as at and r. i flared at its upper end, the shuttle l l pointed at this end so that when the loop of needle thread is dropped over the top of `the shuttle, said loop will pass down between the shuttle and the holder 52 and will be drawn olf at the lower end of the shuttle. The loop of needle thread is taken from the needle after said loop has been drawn through the material by meane of a loop-opener, and said loop-opener is an l ,ran-ged to lspread 4the loop and drop it over.

-.'tlie,shuttle The loop-opener which 'l have herein Ashown comprises two lingers 5l and 55 which are mounted to have a movement l relative to the needle to pitk the loop ot thread oli from the needle, and which also have a movement relative to each other to ,j spread the loop and drop it over the shut Qgtle. The finger is shown as carried by the end of an arm 56 which is swiveled to lanother arm 58that is provided with a roll runs in a cam groove G() formed in a Caliljiember 6ll on the cam-Shaft. The arm 3.0, 58 Vs'niionntedon a stud 57 that is ,ionrnaled `in t.hefraine (see Fig. 23) and 'oy its move mentithe'yrm 5G4is raised and lowered.

i Said "ar'in''t'is swiveled to the arm by providing the former arm with a stud G2 35. which sets in an aperturel in the end of the arm 5S, said stud being locked in place by i the key G3 which ts into a groove formed in the end of the stud G2, and this constrnet-ion permits the arm to swing laterally 40. to cause the fingers 54, 55 to enter the loop 0f needle thread as more fully hereinafter described. The finger 54 is carried hy a slide 65 which slides hack and forth in the arm 56 and which oonnea'ted by a link 4.5 with a lev r G7 that. is pivot/ed to the arm at (3S and that is provirjln'l with a roll 39 Working in a cam groove 'Til formed in a cam member 610 mounted on ille rain-Elea@ 4. Said lever GY is also proided with l 50. roll 71 that works 1n a concentre;

70 operates on the roll thereby' to throw 60 the fingers laterally slightly, io that the;V will enter the loop needle thr ad, and ine cam groove (50 then opera in: to roelr :he

The `n between the am grooves TU and ($0 is such to give the lingers Bland 5.7 a movement away from each other as the arm ISG as: shown in Fig. S, thusiopeningy Vthe loop, and when the loop is opened, the 13am z "oore giv-ts the lever (5T, and consequently the lever .36, a lateral turning movemen. about the stud 62, thus moving the loop laterally, as shown in dotted lines Fig. 2, and passing it over the top of the shuttle, the two sides of the Iloop at thisy time en- -tering the open eide of the shuttle holder. The Cam groeven' 30 and 70 then permit the ingfrs to lowered slightly, and as the fingers drop lfelow the top of the shuttle holder, the loop of thread will be removed therefrom. The Cams GO and 'T0 then return the lingers to their normal position, as shown in t'nll linee in Figs. l and 2. After the thread than looped about the shuttle, theextra length ot' thread used in `forming the loop is talzen np by a take-up mechanism and the stiteh thus formed in the material hy the action of the. needle thread interlocking with the Shuttle thread. This takeup device is in the form of a take-np lever il() carrying the take-np roll 370 over which the thread passes and pivoted to the 'frame at 5l. The lever hatI Connected thereto a link S2 which i5 pivotally eonneeted to an arm 83 that is pivoted to the frame at S-l and that earries a roll adapted to be engaged by a takeaip Cani 85 mounted on the nmin ehaft 5. lith tliiel arrangement the lakenp roll 370 will have a long sweep sntlieient to talie np all-the slark in the loop of the needle thread which waeA pas-eed orer the shuttle. The roll 3T() is shown as carried 'ena bloeit SS that is piroled te the arm 80 'at 89 and this bleek can lfe adjusted by the Setserew 90 so afa to vary the amount of take-np it necessary. While the loop is heilig taken up hv the take-np roll, the thread i5 elamped between the Sonn-e of eupply and the take-np roll so as to prevent the tahwup iti-om drawing more thread from the of supply rather than taking up the i and tightening the stitch.

The normal position'of the thread me/ asurer 10.1 is shown' in Fig. 1 in which position the finger 104 is above' the thread so that the thread will pass straight through te slot 103. This thread measurer 'is capa le of vertical movement relative to the bar 15 and when it is'drawn downwardly, tlie,.finger 104 will engage the thread-and measure off a length, depending on the amount of movement of the thread measurer. The thread measurer is actuated by`an elbovv-leverl05 pivoted to the frame at'106 and acted' ori byl a suitable cam 107 mounted on the-driving shaft 5. A spring 108v surrounding the lower end of the thread measurer serves to v keep the lever 105 in engagement with the cam. The cam. 107 is so' timed- --that thev thread measurer will have its movement at a time when the thread is released bye the thread clamp 93. I make no claim herein tothis thread measurer as ii. has been made the subject of another patent, to wit Patent No.

As stated above, this sewin machine is arranged so that vthe work will efed by the awl, and the work rest 10vis 'provided with a longitudinal slot in which the awl' will move during the'feeding' of the Work. Inorder to give the work its feeding movement,'the aWl-carrier 27 is mounted for horizontal vmovement, and this is accomplished -by' mounting the holder 28so 4,thatjit may have the proper horizontal movement, thuscarry.- ing the awl-carrier andawlwith it. Ihis holder 28'is mounted `to slide'on twostuds 110 and 111 'extending' laterally .from the cheek-piece 112 of the frame and' hasrackf teeth 113 thereon which mesh with alpinion 114 carried by a shaft 115. The shaft has extending therefrom an armll which is adapted to be engaged'by fingers -11'2'`4 and 118 carried by the link 24, so'that as the link rises. and falls, these lingers will engagethe arm 116 at proper times and turn the shaft 115 and pinion 114 first one vway .and then' the other thereby to givethe awll-carrier 'its reciprocating movement.

Smce'the length of 'the `stitch depends v upon the extent of feeding movement given at each reciprocation of the awl-carrler I' have provided for adjusting the length of this movement by adjustably mounting the fingers 117 and 118 on the link 24.A ,The finger 118 is rigidly but adjstably secured to the link, said linger having -ashank 119 which passes through a slot in the link and is secured thereto by a nut 120. This permits t-he finger to be adjusted Vertically,\rela tive to the link.
